BOTTLE-STOPPER.

Specification of Letters Patent- Patented Mar. 26, 1918.

Application filed. May 4., 1917. Serial No. 166,338.

To all whom it may concern:

Be it known that I, CARL BoMEIsLnn, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Bottle- Stoppers, of which the following is a specification.

My invention relates to bottle stoppers adapted to use in closing bottles containing perfumery and the like. In such devices, the cork or stopper is commonly provided with a central opening therethrough and acap mounted on the top of the stopper with an upturned lip or spout in line with the opening to form a pouring orifice. The opening is closed by a cylindrical metal plug, which extends downwardly into the opening from a top which is seated on the cap with the pouring spout or lip contained within a. recess in the lower portion of the plug top. I have found that when the plug is formed of steel, or other relatively inexpensive metal, it becomes corroded by the acid action of the perfumery or similar liquid contained in the bottle which mars its appearance and causes it to stick in the opening. This diliiculty may, of course, be overcome by forming the plug of Monell metal or other non-corrodible metal, but the cost of such construction is excessive. Accordingly, my present invention overcomes this difficulty by forming the plug of steel, or other relatively inexpensive material, and providing the same with a sheathing of tin, or other ditlicultly-corrodible metal, which will not be affected by the action of the liquid in the bottle. This sheathing is preferably formed as a thin sleeve, closed at the bottom, which is driven on to the plug with a tight fit and preferably secured thereto by forcing or swaging the metal sleeve adjacent its upper edge into a shallow groove formed in the plug to receive the same. The sleeves or casings thus provided may be made and mounted on the plugs with a costwhich is much less than that of complete plugs formed of non-corrodible material.

In order that a clearer understanding of my invention may be had, attention is herebydirected to the accompanying drawings forming part of this application and illustrating certain enibodiments of my invention. In the drawings Figure 1 represents a cross-section of a form of stopper having my invention applied thereto, Fig. 2 is a view partly in section and partly in side elevation of my preferred form of plug with the casing about to be mounted thereon and Fig. 3 is a similar view showing the casing mounted in place.

Referring to the drawings, the stopper or cork is shown at 1 having a central axial opening 2 extending therethrough. A metal cap 3 is commonly mounted thereon, having an upwardly extending tubular portion 4: in line with the opening 2 and adapted to form a pouring orifice therefor. This cap may be secured to the stopper in any desired manner, but I prefer to form the cap with a downwardly extending tubular portion 5 which fits within the opening 2 of the stop per, and may be secured thereto by swaging the lower edge of the portion 5 outwardly into the material of the stopper, as shown at 6.

The plug commonly comprises a metallic top portion 7 adapted to seat on the cap 3 and having a recessed portion 8 in which the pouring portion 4 of the cap extends when the top is mounted in position. The plug 9 extends downwardly from the top 7 and may be formed of any relatively cheap metal, preferably steel. The sheathing 10 comprises a thin sleeve of tin, or other relatively non-corrodible metal, which is closed at the bottom, as indicated at 11, and is of proper internal diameter to have a tight fit when driven on the lower end of the plug. Preferably the plug is provided with a shallow circumferential groove 12, into which the metal of the sleeve 10 may be pressed, as shown at 13, to hold the sleeve in position.

When so mounted, the sleeve 10 forms the closure for the opening 2 and fits snugly within the tubular wall 5 of the opening. The top, together with the plug and sleeve, may be easily withdrawn when it is desired to remove some of the contents of the bottle. When the plug is mounted in position, no metal will be contacted by the liquid contained in the bottle, except casing 10, which will not be corroded thereby, it being noted that the resilient material of the stopper presses against the lower portion of the sleeve 10 below the lower edge 6 of the tubular portion 5 of the cap.

What I claim is: 1

1. In a bottle stopper, the combination of a stopper having an opening therethrough,

a cap thereon having a tubular portion extending into the opening, and having an upwardly extending portion in alineinent therewith to form a pouring orifice, a plug having a recessed top adapted to seat-on the cap over said upwardly extending portion of the cap, With a cylindrical portion extending downwardly into said opening, and a thin sleeve of dilficultly-corrodible metal, closed at the bottom, tightly fitted over the lower part of said cylindrical portion and firmly secured thereto, substantially as set forth.

2. In a bottle stopper, a plug construction comprising a top adapted to seat'on the stopper, a metallic plug extending downwardly from the top, adapted to enter the openingthroughthe stopper, and a thin tubularca sing of dilficultly-corrodib1emetal, closed at the bottom and tightly fitted over the plug and fixedly held thereon, said casing being adapted to close the opening through the stopper, substantially as set forth.

This specification signed and witnessed this 27th day of April, 1917.
